the main function of the human heart
Answers
Answer:
the main function of the heart is that it pumps blood throughout the body via the circulatory system ,supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes.
Arterial blood (red,O2 rich blood) flows from heart to each part of the body to provide oxygen and nutrients. Venus blood (blue, O2poor blood) returns from the body to the heart. The blood then travels through the lungs to exchange carbon dioxide for new oxygen. The heart is a pump which moves the blood. Hope it helps
The Heart is a pumping organ that receives blood from veins and pumps it into arteries.
Functions of Heart are:
1. To pump blood across the body.
There is only one function of Heart but this one function is the most important one in our whole body
Heart is a conical muscular double pump structure that brings about circulation of blood in the body. There are four chambers.
Deoxygenated blood from the whole body enters right auricle through a superior vena cava (from upper parts of the body), inferior vena cava (from middle and lower parts of the body) and coronary sinus (from the walls of the heart). Oxygenated blood is carried by pulmonary veins into left auricle from lungs. On being filled, the two auricles contract simultaneously and pass their bloods into ventricles, deoxygenated in right ventricle and oxygenated in left ventricle. The distended ventricles now undergo contraction or systole forcefully. Right ventricle passes blood to pulmonary arch which divides to form pulmonary arteries. Pulmonary arteries take the deoxygenated blood to lungs. Left ventricle passes blood to aorta that supplies oxygenated blood to all parts of the body.
